Build The Earth Notice
Terra 1-to-1 is not affiliated with Build The Earth-- it is a separate mod that is used in their modpack, however we do work directly with the Build The Earth team as Staff. Any and all inquiries about Build The Earth itself should go to Build The Earth.net under the #support and #suggestions channels, not to this GitHub's issues page.
What is it?
Terra 1-to-1 is a Minecraft Forge mod that adds a new world generation type to Minecraft that utilizes public online datasets to generate the earth's structures and features (in Minecraft) without any unfamiliar blocks or biomes at a 1 to 1 scale.
The main features available are terrain, biomes, trees, and roads, all pulled from real global data sources.
The mod is constantly being worked on and being updated as we add more features and fine tune the mod to achieve a better connection between the real world and the world of blocks.
Feel free to check in to this page, and our stream (down below) to always see what is cooking and coming out.
The latest version can always be compiled from Github or downloaded from our unofficial Jenkins CI, which may have features not yet available in official releases on CurseForge. (Warning, maybe unstable)
Feature List
- Concrete Roads, Stone Brick Minor Roads, and Grass Pathways from OpenStreetMap
- (mostly) Accurate elevation and biome placement using public terrain datasets.
- Procedural Tree placement based on a High Resolution Forest Cover dataset.
- Simple Oceans based on elevation with (mostly) accurate depths (this will be improved with the coming Update Aquatic)
- "Customize World" GUI that does not require MalisisCore
- Custom map projections (such as Equirectangular, Sinusoidal, Web Mercator, or EqualEarth)
- Enable or Disable roads (this can also be done by disabling structures)
- Enable or Disable experimental options such as smooth blending (Thanks to KdotJPG for the code)
- Teleport by latitude and longitude using "/tpll latitude longitude [elevation]"
- Use the decimal latitude and longitude format (for example, "/tpll 36.0660 -112.1172" not "36°03'57.6"N 112°07'01.9"W")
- If elevation is left blank, it will place you at the surface at that location
- Ores spawn just below surface (so you don't have to dig over 8000 blocks down to find diamond's if you are on top of Mt. Everest)
- Caves, Dungeons, and other standard underground features are still available and procedurally generated using CubicWorldGen as a baseline
How is it done?
CubicChunks, first of all, adds a 3rd dimensionality to the already existing Minecraft chunk system, allowing much more accessibility when it comes to vertical height (a must have when representing earth, since Mount Everests elevation of 8,848 meters and the oceans depth of 10,994 meters requiring a block limit way higher than measly 256 meters/blocks of vanilla)
CubicWorldGen is an extension mod to CubicChunks to allow generation of worlds with 3 dimensions of chunks rather than the 2 dimensional generation of standard Minecraft.
This mod generates the world using information from public datasets regarding terrain, trees, and human structures with 3 dimensional chunks.
It also stores soil type and climate data within the mod itself to help with (mostly) accurate biome classification
What is the difference this and the between other earth models available in Minecraft?
Rather than being on a percentage scale of the actual world, such as 1:2000 the scale, this generator generates the world on a 1:1 scale (Approximately, actual scale varies based on latitude ). Every block is 1 meter of the real world in every dimension. Because of this, it can have more specific features such as roads and (in a future update) smaller rivers and other bodies of water.

The heights of Mount Everest never felt so virtually high before.

Currently used APIs:
Elevations data is downloaded in real time from AWS Terrain Tiles. (© Mapzen, and others)
Tree cover data is downloaded in real time from the ARCGIS REST TreeCover2000 Image Server hosted by the World Resources Institute, originally from Landsat 7 ETM+ (Originally CC BY 4.0)
Road (and soon, water) data is acquired from OpenStreetMap under the Open Database License. It is downloaded in real-time using a public Overpass API instance. (© OpenStreetMap contributors)
Climate (rain & temperature) data is from The University of Delaware Center for Climatic Research's Climate Data Archive (built into the mod)
Soil suborder data is from the USDA Natural Resources Conservation Service's Global Soil Region Map (built into the mod)

Prerequisites
- REQUIRED: Minecraft Forge for the corrective version of Minecraft of the mod (currently Minecraft 1.12.2, this mod is tested using 2847 and 2768)
- REQUIRED: Standard CubicChunks for the corrective Minecraft version of the mod.
- On GitHub (releases may be out of date, but can be compiled)
- On CurseForge (may be out of date)
- (THE NEWEST VERSION OF THE CUBICCHUNKS MOD FOR ALL VERSIONS IS ALWAYS AVAILABLE ON THE CUBIC CHUNKS DISCORD under the #info-new-cc channel)
- REQUIRED: Standard CubicWorldGen for the corrective Minecraft version of the mod VERSION 0.0.85.0 OR HIGHER IS HIGHLY RECOMMENDED
- On GitHub (releases may be out of date, but can be compiled)
- On CurseForge (may be out of date)
- (THE NEWEST VERSION OF THE CUBICCHUNKS MOD FOR ALL VERSIONS IS ALWAYS AVAILABLE ON THE CUBIC CHUNKS DISCORD under the #info-new-cc channel)
- Recommended: Malisis Core: (The Planet Earth generation at the current moment does not have any support for Malisis, and is a future plan, but the original generation methods inside of CubicWorldGen do support Malisis)
You must have all required mods installed for the Planet Earth generation to work!!!
CubicWorldGen 0.0.85.0 or later is HIGHLY recommended, as it has changes made that no longer causes conflicts with CubicWorldGen's default "Custom Cubic" generator, with the Terra 1-to-1 Planet Earth generator.
